WILLIAIVI GOSSETT, OF FALLS CITY, NEBRASKA, ASSIGNOR, BY MESNE ASSIGNMENTS, OF ONE-HALF TO DANIEL SCOTT, ROBERT BATES, AND THOMAS MURPHY, ALL OF FALLS CITY, NEBRASKA.

SECTIONAL ARCH.

To all whom it may concern:

Be it known that I, IVILI'JAM Gossn'r'r, a citizen of the United States, residing at Falls City,l in the county of Richardson and State of Nebraska, have :invented certain new and useful In'ipro'vements in Sectional Arches, of which the following is a specification.

My invention relates to iniprovements in concrete construction, and has particular reference to an arch, bridge, culvert, sewer, or like construction.

One object of my invention is the provision of an arch, bridge, culvert or sewer as the circumstances may require, which will be portable, adjustable and capable of construction with case and facility, and which will be thoroughly efficient and practical in every particular.

Another object of my invention is the provision of a concrete construction of the character and for the purpose named which will be made of sections, which sections can be quickly assembled, which will be properly braced and reinforced, the construction possessing strength and durability and presenting a compact and attractive appearance.

Another object of my invention is the provision of a concrete construction of the character named which will possess the necessary requirements of strength and durability, which will not be affected by weather conditions, which will be capable of production at a comparatively low cost, thus possessing the necessary requirements to connnend the construction as desirable for the purposes stated.

IVith these objects iu view, my invention consists of a concrete construction adapted for use in the building of arches, bridges, eulverts, sewers, and other character of constructions embodying novel features of construction and combiiiation of parts substantially as disclosed herein.

In order that the details of construction of my improvement may be readily understood and the numerous advantages thereof be fully appreciated, I have illustrated in the accoi'npanying drawings concrete constructions embodying my invention.

represents a perspective and sectional view of a part ot' a construction on an enlarged scale of the form of my invention shown in Fig. Q. Fig. ll represents a transverse sectional view of a slightly modified construction of my invention. F ig. 5 represents a transverse sectional` view of another slightly modified construction. Fig. (3 represents a perspective and sectional view of the form of my invention shown in Fig. It. Fig. 7 represents a detailed view of the tie, jamb, or brace rod, and Figs. 8 and 9 represent detailed views of a cistern top construction.

Referring by numerals to the drawings, in which similar numerals of reference are used to designate corresponding parts in all the views of the drawings: The numeral l designates the side walls of a bridge or arch, constructed of masonry and provided at the top with a channeled or recessed portion 2.

It' desired, instead of the masonry con struction 1, I may use the pillars or columns 3, upon which may be supported the pair of longitudinal members 4, each provided with a channel or recess 5, it being understood that I provide the walls or supports of masonry or the pillars as occasion may require.

Upon the pillars or walls is mounted and supported my concrete construction which as before stated is particularly adapted Jfor arches, bridges, culverts, sewers or like construction, and I use a series of members 6, provided with the broad supporting portions 7, and which are braced and secured upon the supports by means of the vertical pins S. The upper ends of the sections interlock by means of the curved portion 9, and the receiving recess 9*, and the parts at their point of contact fit snugly together' and are .locked in position by means of the horizontal transversely disposed pins l0. rlhe sections flare at vll and form the channel l2 in which may be placed the filling 13, of concrete, and to secure the sections and properly brace said sections I use the longitudinal tie rods llt, provided with retaining nuts l5, and with engaging plates 16. In this manner the construction consists of a series of sections which are properly interlocked and braced, and are secured together thus, making a sectional construction which is easily assembled and which is portable, permitting transportation from place to place with ease and facility.

In the forms of my invention shown in Figs. l, 4, 5, and 6, the arch or bridge consists only of series of pairs of sections, and the pairs are connected together by the longitudinal dowels or pins 17, seen most clearly in Fig. 6, and in Figs. 2 and 3, I show the construction in Which the sides of the arch are each composed of two sections 6, and it Will be understood that I may use as many pieces or sections in my construction as desired according to the Work for which the construction is designed.

It is evident that I provide a concrete construction Which is capable oi use under many conditions, Which is portable, permitting ready and easy transportation, which can be quickly assembled or taken apart if necessary, and Which in fact embodies every requirement to commend the construction as desirable and practical.

I claim:

l. In concrete construction, the combina-A tion With the supportingmembers, of means providing` a flat rest for 'the base of the arch and a flange or rim for preventing the lateral movement of the arch, a series of interlocking sections forming an arch mounted on said rest, means projecting vertically from said sections and engaged in the rest for securing the sections thereon, pins engaged in adjacent sections for securing them together, and triangular projections extending longitudinally of the sections at their intersecting edges, said projections thus forming a groove, and means for laterally bracing the sections and for clamping them longitudinally together inserted in the spaces or grooves thus formed. Y

2. In a sectional arch, the combination With the supports having a liat top terminating at its outer edge in an abutment shoulder formed thereon, of a series of sections mounted on the supports, said sections being provided with interlocking rounded grooves and projections, means having their ends engaged in adjacent sections for locking the same securely together, vertically extending means for locking the base sections to the supports, horizontally longitudinally disposed means for locking the ends of adjacent sections together, and triangular proj ections formed on the upper face of the sections on the edges thereof and extending longitudinally of the sections said projections thus forming a groove, a suitable liller packed into the groove or recess thus formed between the sections and making a iiush joint with the tops of the projections and serving to make practically an integral arch of the various sections and to prevent Water or other matter from passing through the joints of the sections, and a tie rod embedded in said filler and extending the length ot the arch for locking the sections together and bracing them against longitudinal strain.

In testimony whereof I altix my signature,I in presence of witnesses.
